使用ssl的Spring 5 WebClient

Question

我试图找到WebClient使用的示例。

我的目标是使用Spring5 WebClient使用https和自签名证书查询REST服务

有什么例子吗？

看起来Spring 5.1.1（Spring boot 2.1.0)从ReactorClientTtpConnector中删除了HttpClientOptions，因此在创建ReactorClientTtpConnector实例时不能配置选项

现在起作用的一个选择是：

val sslContext = SslContextBuilder
            .forClient()
            .trustManager(InsecureTrustManagerFactory.INSTANCE)
            .build()
val httpClient = HttpClient.create().secure { t -> t.sslContext(sslContext) }
val webClient = WebClient.builder().clientConnector(ReactorClientHttpConnector(httpClient)).build()

基本上，在创建HttpClient时，我们配置了不安全的sslContext，然后将此HttpClient全局传递给ReactorClientHttpConnector中使用。

val sslContext = SslContextBuilder
            .forClient()
            .trustManager(InsecureTrustManagerFactory.INSTANCE)
            .build()
val tcpClient = TcpClient.create().secure { sslProviderBuilder -> sslProviderBuilder.sslContext(sslContext) }
val httpClient = HttpClient.from(tcpClient)
val webClient =  WebClient.builder().clientConnector(ReactorClientHttpConnector(httpClient)).build()

• https://netty.io/4.0/api/io/netty/handler/ssl/util/IncisureTrustManagerFactory.html

更新：相同代码的Java版本

SslContext context = SslContextBuilder.forClient()
    .trustManager(InsecureTrustManagerFactory.INSTANCE)
    .build();
                
HttpClient httpClient = HttpClient.create().secure(t -> t.sslContext(context));

WebClient wc = WebClient
                    .builder()
                    .clientConnector(new ReactorClientHttpConnector(httpClient)).build();
